CreateYourOwnMagicalWorldsInDisneyInfinity:ToyBox

Disney has a brand new iPad application in the App Store. Called Disney Infinity: Toy Box, the app allows users to create their own magical, virtual worlds using Apple's tablet, featuring all manner of characters and creatures from some of Disney's (and Pixar's) most popular movies.
Best of all, Disney Infinity: Toy Box can be downloaded free of charge, and the app is optimized for the iPad only. "Captain Jack Sparrow in a sports car racing Dash, Sulley climbing mountains to find Cinderella’s Castle – create anything your imagination dreams of," Disney explains in the application's release notes.
You can also sync Disney Infinity: Toy Box with an Xbox 360, PlayStation 3, Wii, Wii U, and Nintendo 3DS in order "to unlock even more props, characters, and decorations."
As outlined in the app's release notes:
